I’m not sure I would say it’s not popular. I hear it a lot during Christmastime, and I personally enjoy it, I just wouldn’t say it’s my favorite per se 
This song is perfect for people who want to listen to Christmas music but don’t want to do so before Thanksgiving (although I guess it’s a little too late for that now lol

Man, I haven’t listened to BarlowGirl in forever! “Never Alone” is still gets stuck in my head to this day.
